A
choir (also known as a
chorale or
chorus) is a
musical ensemble of singers.
Choral music, in turn, is the music written specifically for such an ensemble to perform. Choirs may perform music from the
classical music repertoire, which spans from the Medieval era to the 2010s, and/or
popular music repertoire. Most choirs are led by a
conductor, who leads the performances with arm and face gestures.
